ActivePlastics - Polyether polyols - Part 4: Determination of sodium and potassium
塑料 聚醚多元醇 第4部分：钠和钾的测定
Application Summary AI generated
This standard specifies the flame photometric method for determining sodium and potassium content in polyether polyols, which are key raw materials for polyurethane production. It is applied in quality control laboratories within the chemical and plastics industries to ensure that residual alkali metal levels meet specifications for downstream applications like flexible foams, coatings, and elastomers. The testing is critical for preventing catalytic interference and product defects during polyurethane manufacturing.
